Specification of Letters Patent N0. 12,239 dated anuary 16, 1855.

T0 all w7wm z'zf mag; concem:

Be it known that I, MICHAEL B. DYOTT, of the oity of Philadelphia and Stute of Pennsylvania, have invented and made a new and useful Improvement in the Construction of Shade Holders und Proteotors 130 be Used Upon Lamps or Gas-Lights; and I do deolare the following to loe a full and exacc description of their constrction und use, referring to ehe annexed drawings, which form a part of this specifioation, in whioh Figure l is a vertical section of the shade holder and-proteotor Wih the shade (which is also in section) placed upon it. Fig. 2 is a perspective representation of the shade holder and proteotor (which I shall hereafter designate by the name of shield) without the shade being placed upon it.

Similar letters of reference indicate corresponding arts in euch of the several figures.

The nature of my invention and improvement consists in placing within the upper portion or neok of the shade (A) a metalic or inoombustible shield (B) between which is maintained a sufficient space for the passage of air to keep the shade cool and to protect it from being burned if made of paper (which is now mo-st generally used) or i:E made o-f metal gilded or painted, from being Scorched and otherwise disfigured.

T0 enable those skilled in the art to make and use my invention I hereto annex a full description o-f the same.

The shade (A) as illustrated in the seetional drawing (Fig. l) is made of paper, and in the usual dome form, but may be made of any other material and of any desired ferne, but t-he shield (B) must be made of metal or some inoombustible material, a1'id may correspond in form to ehe iriside of t-he shade. It should be es niuch less in diameter than the shade as to leave a suflicient space for the free passage of air between them to keep the shade cool.

The shield should extend upward through the neck o1 opening of the shade, enough to protect the shade from the frame, and doWnward a suflicierit distance to effeotually guard it from the heat. There are four or more small pieces of wire (C) plaoed upon the outside of the shield for the purpose of holding t-he shade ofl' the -proper distance from the shield to admit the passing of a suflioiency of air to keep it cool. The passage of the 2iir is indicated by the arr0ws in FIg 1F (D D) are wiresiaitac'hed ab their upper end to the lower edge of the shield and to to a collar (F), which fits upon the' gas burner (E) to support and hold the shield and shade in their proper osition (G) is the flame of an ordinary gas brner and shows its relative position to the shield and shade es illustrated in Fig. l.

Its operation is so plainly portmyed in the. foregoing description that further reference to that subject is unnecessary, and its advantages are so self evident that it is scarcely necessary to nenne them. I will therefore simply say that by the use ofthe above described shade holder and shield, we are eriabled to contract the opening in the top of the shade, and thus render theshade doubly .effective, in reflecting downward the light, Which is the principal office or intentio-n of the shade, thus 2Lddihg greatly to its urility, 2 1s well as its beauty, and as in the use of these articles it is desirable that they should be semi-transparent, in Order to refieot ehe light and at the same time not to obscure thelight unneoessarily, they are generally made of paper or some cornbustible material, and the places where they are most usecl demands considerable ornamentati0n and taste in their a1opearance, and consequent eost in their manufacture. It is therefore peculiarly desirable that sonne efii'eotual means should be devised to proteot them from being burned, disfigured end destroyed, which frequenfly happensthe first t-ime they are used, the lose of which would be suflicient to warrant the trifling additional cost of such a proteotor as is above described. But when it is taken in oonsideration that it endangrs by fire a vast am'ount of property and lives the utility and necessity of such a protector is much more obvious, as by its use all kinds of shades may be used with perfect safety from being burned if made of eombustible material and from being discolored, scorched, und. disfigured, if made of metal, und for the salze of dist-inction, I shall call my invention the safety shade holder and protector.

VVhat I claim as new und desire to secure by Letters Patent is The arrangement of the shade A, shield B zind wires or their equivalents C With the intervening space, substant-ially as desoribed for the prot eotion of -the shade as herein specified.
